All of the images is archived from every UAV. The persistent monitoring means that any past time can be selected for a monitored area and what happened at that time can be played as if you were watching it live. The current system has 1.8 gigapixel video but DARPA has another project that will soon have 50 gigapixels of resolution and mass production will drive the cost to about $1000. 50 gigapixels would mean increasing resolution to make out 1 inch objects from 17500 feet or viewing a larger area at the 6 inch resolution. A live and historical feed of everything in Manhattan down to 1 inch resolution from one drone.
